Abstract
A lighting device includes a light-emitting element, an ultrasonic member, a signal processing unit, a light control unit, an indicator and an indicator control unit. The light-emitting element emits a light. The ultrasonic member emits an ultrasonic signal and receives the ultrasonic signal reflected from an object. The signal processing unit is communicated with the ultrasonic member for converting the reflected ultrasonic signal into a control signal. The light control unit is interconnected between the signal processing unit and the light-emitting element for controlling the light-emitting element to emit light in a selected operating mode in response to the control signal. The indicator control unit is interconnected between the signal processing unit and the indicator for controlling the indicator to assert a notification signal indicative of the operating mode in response to the control signal.
